Mark Zuckerberg is expected to dish out another mea culpa on Tuesday when he meets with members of the European Parliament on Tuesday about the Cambridge Analytica scandal, the New York Times reports.

Why it matters: Zuckerberg's testimony will come days before Europe rolls out the General Data Protection Regulation, which is intended to give users more control of how their personal data is used and streamline data processes across the EU. The measure gives European regulators the power to fine companies up to 4% of their global revenue for violations, which, per The Times, would equal $1.6 billion for Facebook.
